In what year was the Constitution written?

The Constitution of the United States was written in 1787 during the Philadelphia Convention. This pivotal gathering of delegates was convened to address the weaknesses of the Articles of Confederation, leading to the creation of a stronger federal government with a system of checks and balances. The final draft of the Constitution was completed in September of that year and subsequently ratified by the states.

The other years mentioned are significant in American history, but they refer to different events. 1776 is the year the Declaration of Independence was adopted, marking the colonies' break from British rule. 1791 is notable for the ratification of the Bill of Rights, which comprises the first ten amendments to the Constitution, providing essential protections for individual liberties. 1789 is important as it is the year the Constitution went into effect after being ratified by the necessary states and the new federal government was established.
